Construction sealants and adhesives
Books and Publications Durable Concrete Structures Design Guide Comitb Euro-international du Beton Thomas Telford, 1992 112 pp, £45 (Hardback) ISBN 0-7277-1620-4 Since the late 1970s the CEB has been active in solving the technical aspects of premature failure of concrete structures. Task Group No. 20, Durability and Service Life of Structures, has produced four works that have been incorporated into this design guide following consideration of comments and proposals. Practising engineers will find this book more appropriate than materials specialists. The presentation is based on simplified models of degradation mechanisms and influencing factors which are consistent with the complicated physico-chemical mechanisms that determine the intensity of degradation and the consequential deterioration of concrete in structures. The book is divided into three sections. • • •
Part l Theoretical Background Part 2 Recommendations Appendix, References, Bibliography
Presentation follows a logical approach in Part 1. Transport mechanisms are presented which illustrate how the structure of concrete becomes influenced by its surroundings, i.e. gases, moisture and deleterious agents. This is then developed to illustrate the effect on the physical properties of concrete. The book contains diagrams, tables and figures that clearly act as aids to the text. Both the quality of the print and the composition of the illustrations are admirable. Part 2 is devoted to recommendations that follow from avoiding the effects that can occur as described in the first part. In this context, classification of the environment is divided into nine sections defining increasing severity of the environment. Other tables denote exposure classes for reinforcement and chemical attack. One table that appears rather optimistic in its recommendations is table 12.1 which outlines minimum mix requirements related to the nine classes of environment mentioned earlier. The topical subjects like ASR and chloride-induced corrosion are dealt with as well as concrete in marine environments. Appendix 1 on the curing of concrete structures is interesting but a little 'heavy' for the intended reader, the practising engineer.

References are included that confirm the international input of the book which is again confirmed in the bibliography. This is an excellent book that conveys the essence of latter day concrete technology in a mere 112 pages of A4 print. A worthy addition to one's library. G. True Stanger Consultants Midlands Region
Construction Sealants and Adhesives Julian R. Panek and John Philip Cook John Wiley Third Edition, 1991, 375 pp. ISBN 0-471-53474-9, £51.00 This book is an update on the second edition published in 1982. It is aimed at architects and students and offers a useful presentation on the latest technology on sealants, gaskets, tapes, waterproofing membranes, and silicone structural sealant glazing. Perhaps the majority of the book relates to the generic types of building sealants. However, sections are devoted to sealants in highway construction, bridge expansion joints, membrane waterproofing, etc. The applications chapters are of particular interest due to the combination of relevant narrative and clear illustrations which combine to present the information in a concise manner. Readers may be especially interested in the properties of both silicone and urethane sealants. An example is given of a 7 inch wide expansion joint which was installed to compensate for + 2 5 % joint movement in a poorly designed curtain wall. Unfortunately the book is centred around American practice with little if any reference to British or European techniques. Perhaps these are similar? This may limit the interest outside the USA to using the book not as a prime reference source, but more as a knowledge extender. Although others may find this book irrelevant because of this bias, it is a comprehensive practical construction guide that will provide useful information to all those prepared to consult its 375 pages.

BRE profiles Europe's setting of common concrete standards BRE research has found significant differences in concreting practice across Europe which have implications for the development of common rules on concrete quality. BRE Information Paper 6/ 93 'European concreting practice: a summary' provides a comprehensive review of concrete construction in the 15 member countries of the European Committee for Standardization (CEN) prior to the implementation of unified European standards. The findings were obtained from questionnaires returned by participating member countries on various aspects of current practice with respect to durability, including specification parameters, workability values and compressive strength testing. It concludes that differences in concreting practice reflect variations in Europe's climate and industrial culture, and that the development of common standards must make provision for the complete range of climate and microclimate experienced within the CEN area. Copies of 'European concreting practice: a summary' and of the individual Information Papers on Germany, Sweden, Italy and France are available from the BRE Bookshop, Building Research Establishment, Garston, Watford WD2 7JR, price £3.50 each (plus 35p p&p).
